If he has a wii, he may as well get "Strikers Charged".
I suggest getting both of the Baten Kaitos Games, WWE Day of Reckoning 2 (best game since the the n64 games), Simpsons Hit-n-Run (I liked it), Beyond Good and Evil (though if you have a soul, you will buy the game as it needs all the support it can get) and also the Timesplitters games.
